Abstract

La invención se relaciona con un método para producir agregados de composiciones de cemento no endurecido, en particular de concreto o concreto, residual, el método que comprende agregar a) un agente absorbente de agua y b) un desactivador de cristalización a una composición de cemento no endurecido y mezclando hasta que se forme un material granulado. El método permite convertir los residuos innecesarios de concreto líquido en un producto práctico, el cual puede reutilizarse para producir nuevas composiciones de concreto. La invención además se relaciona con un material de cemento granulado que se puede obtener de acuerdo con método correspondiente, para el uso de dicho material de cemento granulado como un aditivo para composiciones de cemento, y combinaciones de aditivos para composiciones de cemento, cuyas combinaciones de aditivos comprenden un agente absorbente de agua y un activador de cristalización.The invention relates to a method for producing aggregates of unhardened cement compositions, in particular concrete or residual concrete, the method comprising adding a) a water absorbing agent and b) a crystallization deactivator to a non-hardened cement composition. hardened and mixing until a granular material is formed. The method enables unnecessary liquid concrete waste to be converted into a practical product, which can be reused to produce new concrete compositions. The invention further relates to a granulated cement material that can be obtained according to a corresponding method, for the use of said granulated cement material as an additive for cement compositions, and combinations of additives for cement compositions, which combinations of Additives comprise a water absorbing agent and a crystallization activator.
